In this configuration, the PDC transfers only the DATA. The Identifier must be read by the user in
the LIN Identifier register (US_LINIR). The LIN mode must be written by the user in the LIN
Mode register (US_LINMR).
The WRITE buffer contains the DATA if the USART sends the response (NACT=PUBLISH).
